My understanding is that the long and short of it is that you should not try to get a WiFi router at all and instead have a wired router and one AP. There is nothing inherently making it a bad idea to bundle those things in one device, but unless you want to go down the DIY rabbit hole, the AIO options are generally not great. Manufacturers I think you should consider would be MikroTik, and Netgear's business and SOHO ranges (one step up from the normal consumer stuff). If you're set on a consumer WiFi router device, Unifi is your best bet. Other than that, Linksys and Asus aren't that horrible, relatively speaking, and you can pick a device with good Open/DDWRT support if you retire it or change your mind down the line. How important the above is also depends a lot on your requirements in terms of # connections, throughout, and consistency.
